Study Summary
The goal of this study is to find an effective treatment for chronic patellar tendinopathy (PT). Investigators will conduct a 32-week randomized controlled clinical trial to determine whether platelet rich plasma (PRP) injections improve disease-specific clinical outcomes with correlation to a new method of ultrasound (US) imaging assessment called Acoustoelastography (AE). Positive findings of PRP compared to control would suggest future larger scale studies to help establish an optimal protocol for the nonsurgical management of PT.
Primary Outcome
Participants will complete outcome questionnaires at baseline and 32 weeks. The results will evaluate pain- and function-dependent, knee-specific quality of life, as assessed by composite scores on the validated Victorian Institute of Sport Assessment-Patellar (VISAP). The total possible range of scores is 0-100 with higher scores indicating fewer symptoms and higher function.
Interventions
- OTHER saline
- BIOLOGICAL platelet rich plasma
